VarioCam Plus System.
VarioCam Plus combines variable-
valve timing with two-stage l ift
on t he inlet side. This results in
smoother running, better fuel
economy and lower exhaust
emissions. As well as greater top-
end power and low-end torque.
This two-in-one engine concept
seamlessly adapts in response
to driver input. The res ult:
instant acceleration and
extremely smooth running.
The variation in intake timing is
steplessly controlle d by means
of an electrohydraulic rota ry
vane adjuste r at the head of
the corresponding camshaft.
To improve throttle response
during the warm-up phase,
VarioCam Plus selects high valve
lifts with retarded valve timing.
In the middle and low load ranges,
low valv e lifts w ith advanced
timing reduce fuel consumption
and exhaust em issio ns. High
valve lifts genera te high torque
and maximum output.
